KrosFlo Research IIi Tangential Flow Filtration system
Spectrum Laboratories introduced the new KrosFlo Research IIi Tangential Flow Filtration (TFF) System. The system—perfect for R&D scale microfiltration and ultra-filtration processing—comes with the digital pressure monitor integrated into the peristaltic pump. Both the pump and pressure monitor functions are controlled by the same PLC/HMI. Four pressure measurements are displayed including feed, retentate, permeate and transmembrane pressure. The system has audible and visual low-, high-pressure alarms for the inlet and a high-pressure pump shutoff that helps maintain membrane integrity and achieve high product recovery, Spectrum reports. The KFComm data collection software included with the system interfaces with a computer to download real time process data to an Excel file. The information captured includes pressures and flow rates. The software also calculates and trends transmembrane pressure, filtration flux, shear, volumetric throughput and the concentration factor.
